Chef Jean's Alfredo Sauce

This is very simple and has two "secret" ingredients to jazz it up a bit(gorgonzola and lemon zest). The parmesean cheese amount is an estimate, I just use enough to thicken the sauce, adjust as needed.

I excitedly mentioned that I was going to surprise my husband with his all time fav...Alfredo, but someone here obviously couldn't contain himself. Telephone call as recounted by DH--Caller: Husband, is that you? DH: Who's this? Caller: Your wife. When are you going to be home for dinner? DH: That doesn't sound like you? Caller: I'm, uuurrr ummm, a little congested. DH: Seriously, who's this? Caller: buuuummmmmmmmmmmm. Minutes later DH comes home telling of a practical joker impersonating me. You can't turn your back for one second on Pepper, my cockatiel. I'm becoming suspicious of his plans of a hostile takeover.
